You decide not to use the condom

You toss the condom out the window, even though you had gotten it out of the
glove compartment. With hard, naked cock in hand you decide to take Carmen
a la naturual. Spreading her legs gently and bunching up her skirt, you position
your hard waiting cock at the entrance of Carmen's unsuspecting pussy ...

...

Carmen slowly opens her eyes as she feels your cock rub against her entrance.
"What? ... what's going on," Carmen asks huskily, as she turns to look at you. She
sees what you're about to do and moans, "No ... wait." But it's too late as you
begin to sink your cock into her warm pussy.

"Mmph! groans Carmen as she feels your cock push into her tight virginal pussy.
She sighs and groans, confused as to what to do.

In and out, you slide ... slowly lubing your cock with her juices, then finally ...

"Stop! Wait, pull it out!" Carmen squeals, as she pushes against your chest and
pulls away from you. "I ... I was saving myself!" yells Carmen angrily, as she
begins to put on her clothes.

...

In the end, Carmen was rather upset with you sliding your cock into her. Although
you did not actually take her cherry, Carmen was upset enough to think that you
ruined her. So much so she refused to see you ever again.
